This site loads a wonderful ad script from http://www.clicks4u.com/watermark.js

This most excellent script has the following code (condensed, with irrelevant
parts removed):

function watermark () {
  var wm;
  if (navigator.appName == "Netscape") {
    if (navigator.appVersion.indexOf("6") == -1) {
      wm = document.jsbrand;
    }
  }
  if (navigator.appVersion.indexOf("MSIE") != -1) {
    wm = document.all.jsbrand;
  }
  if (wm)
  { /* do something }
  else 
  {
    setInterval("watermark()",100);
  }
}
setInterval("watermark()",100);

Now this script executes and calls the outer setInterval.  This makes the
function watermark() run every 100ms from that point on.  When this function
runs, it checks what sort of browser this is.  If it's not IE or Netscape 6, it
setIntervals itself again.  Thys now every 100ms two copies of the function run.

You get exponential growth, with the number of intervals set doubling every
100ms.  Unsurprisingly, this chews up lots of CPU and memory.

I see the same behavior in Netscape 4, Opera, Konqueror, and Netscape 7 (since
the site only checks for 6!).

Over to evangelism... this is just designed-in infinite exponential growth.

That's

   { /* do something */ }

of course.

Original URL is gone.  http://www.clicks4u.com/watermark.js is still available.  
The following site uses this script:

No problems manifested when I opened this site.

Jeff - This appears to be RESOLVED when I visit the URL in your bug description.  The URL source does not seem to reference the "watermark.js" script anymore.  Close bug?

The technical problems with clicks4u.com seems to have been resolved by the US economy crashing.  After six years I guess that's good enough.

In TE, we usually resolve these FIXED (BYDEATHOFSITE).

Comment 7 may be the best bug resolution comment in all of Bugzilla.
